Method for actuating a hydraulic vehicle brake system

摘要

A method for actuating a hydraulic vehicle brake system, includes a master brake cylinder with a preferably electromechanical brake booster and a wheel slip control device. The master brake cylinder is actuated simultaneously with the brake booster, and hydraulic pumps of the wheel slip control device are driven by an electric motor. Pressure builds more quickly in the wheel brakes of the vehicle brake system for safety and assistance functions that require high pressure build-up dynamic. The method also increases the wheel brake pressure using the pressure that can be generated by actuating the master brake cylinder with the brake booster.

1. A method for actuating a hydraulic vehicle brake system having (i) a hydraulic master brake cylinder, to which at least one hydraulic wheel brake is connected, (ii) a controllable brake booster, and (iii) a wheel slip control device including a hydraulic pump configured to generate a wheel brake pressure in the at least one wheel brake, the method comprising:
opening an intake valve, which hydraulically connects the brake booster to a suction side of the hydraulic pump; actuating the master brake cylinder with the brake booster in order to provide an increased pressure to the suction side of the hydraulic pump and actuate the at least one hydraulic wheel brake without actuation of the master brake cylinder by muscle force; and operating the hydraulic pump simultaneously with the actuation of the master brake cylinder with the brake booster without actuation of the brake master cylinder by muscle force to generate the wheel brake pressure in the at least one wheel brake.
